A confession. I was good at drawing, so much so that I could take a photo of a footballer's signture and with a bit of practice produce a likeness, on demand, that would pass muster. I suspect that it would have given a run for its money to the technique outlined in this article using holography to reconstruct the way that a signature was produced. Though I kind of wonder whether it will get a mush use as all that with digital messaging and PIN's -how often are we going to be signing things?
